Interesting story. Seems there are a lot of 2k/XP systems out there
without adequate Administrator passwords. No administrator password
means instant access to the C$ share...i.e. entire hard drive including
startup folders. Even a weak password makes the system vulnerable
as the Administrator isn't locked on unsuccessful password guesses
as shipped.
A lesson for those networks that block netbios by blocking port 139. 445
needs to be blocked too.
Another risk mitigation step is to use the Local or Group Security
Policy to deny network access to the Administrator account.
